// Usage: node scripts/validate-suite.js [test-glob-pattern]
// Runs the project's test suite (node --test) and fails if any test fails.
// When called without arguments, runs all tests in test/.
// When called with a glob pattern, runs only matching tests.
//
// This script is intended to be used as a Gene validation command.
// It provides stronger assurance than validate-modules.js (which only
// checks that modules can be loaded).
